Airworthiness Directives; Airbus Model A310 Series Airplanes, and 
Airbus Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and 
Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series 
Airplanes)

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are superseding an existing airworthiness directive (AD) 
that applies to the products listed above. This AD results from 
mandatory continuing airworthiness information (MCAI) originated by an 
aviation authority of another country to identify and correct an unsafe 
condition on an aviation product. The MCAI describes the unsafe 
condition as:

    Prompted by a reported in-service event, EASA issued AD 2009-
0084 to prevent unwanted movement of pilot- or co-pilot seat in the 
horizontal direction which is considered as potentially unsafe, 
especially during the takeoff phase when the speed of the aeroplane 
is greater than 100 knots and until landing gear retraction.

* * * * *
Uncommanded movement of the pilot and co-pilot seats during takeoff or 
landing could interfere with the operation of the airplane and, as a 
result, could cause loss of control of the airplane. We are issuing 
this AD to require actions to correct the unsafe condition on these 
products.

DATES: This AD becomes effective April 26, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain other publications listed in this AD as of April 
26, 2011.
    The Director of the Federal Register approved the incorporation by

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on December 1, 2010 (75 
FR 74665), and proposed to supersede AD 2009-11-09, Amendment 39-15919 
(74 FR 25399, May 28, 2009). That NPRM proposed to correct an unsafe 
condition for the specified products. The MCAI states:

    Prompted by a reported in-service event, EASA issued AD 2009-
0084 [which corresponds to FAA AD 2009-11-09] to prevent unwanted 
movement of pilot- or co-pilot seat in the horizontal direction 
which is considered as potentially unsafe, especially during the 
takeoff phase when the speed of the aeroplane is greater than 100 
knots and until landing gear retraction.
    AD 2009-0084 required the deactivation of the electrical power 
of SOGERMA pilot seats P/N 2510112 series and co-pilot seats P/N 
2510113 series. Optional intermediate actions were also provided by 
AD 2009-0084 to allow partial or full restoration of seat adjustment 
functionality.
    Since AD 2009-0084 was issued, a permanent solution has been 
developed that terminates the de-activation requirement and 
invalidates the intermediate actions.
    Consequently, this AD retains requirements of EASA AD 2009-0084, 
which is superseded, and requires implementing the terminating 
action. In addition, this AD prohibits the (re)installation of 
unmodified pilot- and co-pilot seats on any aeroplane that has been 
modified in accordance with the requirements of this AD.

Uncommanded movement of the pilot and co-pilot seats during takeoff or 
landing could interfere with the operation of the airplane and, as a 
result, could cause loss of control of the airplane. You may obtain 
further information by examining the MCAI in the AD docket.

Relevant Service Information

    Since issuance of the NPRM, Airbus has issued Mandatory Service 
Bulletin A310-25-2205, Revision 01, dated November 19, 2010. This 
revision does not require any additional work. The actions described in 
this service information are intended to correct the unsafe condition 
identified in the MCAI. We have updated this final rule to refer to 
Airbus Mandatory Service Bulletin A310-25-2205, Revision 01, dated 
November 19, 2010. We added a new paragraph (n) of this AD to provide 
credit for doing actions before the effective date of this AD in 
accordance with Airbus Mandatory Service Bulletin A310-25-2205, dated 
August 31, 2009, for Airbus Model A310 series airplanes.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    We reviewed the available data, and determined that air safety and 
the public interest require adopting the AD with the changes described 
previously.

[[Page 15806]]

We determined that these changes will not increase the economic burden 
on any operator or increase the scope of the AD.

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have required different actions in this AD from those 
in the MCAI in order to follow our FAA policies. Any such differences 
are highlighted in a NOTE within the AD.

Costs of Compliance

    Based on the service information, we estimate that this AD affects 
about 132 products of U.S. registry.
    The actions that are required by AD 2009-11-09 and retained in this 
AD take about 2 work-hours per product, at an average labor rate of $85 
per work hour. Based on these figures, the estimated cost of the 
currently required actions is $170 per product.
    We estimate that it would take about 2 work-hours per product to 
comply with the new basic requirements of this AD. The average labor 
rate is $85 per work-hour. Required parts would cost about $5,000 per 
product. Where the service information lists required parts costs that 
are covered under warranty, we have assumed that there will be no 
charge for these costs. As we do not control warranty coverage for 
affected parties, some parties may incur costs higher than estimated 
here. Based on these figures, we estimate the cost of the AD on U.S. 
operators to be $704,880, or $5,340 per product.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. ``Subtitle VII: Aviation 
Programs,'' describes in more detail the scope of the Agency's 
authority.
    We are issuing this rulemaking under the authority described in 
``Subtitle VII, Part A, Subpart III, Section 44701: General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We determined that this AD will not have federalism implications 
under Executive Order 13132. This AD will not have a substantial direct 
effect on the States, on the relationship between the national 
government and the States, or on the distribution of power and 
responsibilities among the various levels of government.
    For the reasons discussed above, I certify this AD:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979); and
    3. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains the NPRM, the regulatory evaluation, 
any comments received, and other information. The street address for 
the Docket Operations office (telephone (800) 647-5527) is in the 
ADDRESSES section. Comments will be available in the AD docket shortly 
after receipt.
